Tales from the pit

It was about three yrs ago,me and two of my friends drove from Oklahoma to Kansas City for the Mayhem Festival. I was pumped to see all the bands including SLAYER!!! They opened with Raining Blood, a pit breaks out i don't hesitate and jump in, The song ends and this guy comes up to me and says "You need to calm down a little". (I look at him confused i did nothing out of the norm i wasn't hurting anyone ). Finally said "Ok ill calm down when Kerry King puts down his guitar,gets off the stage and tells me too calm down"
